Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 3; Dorsale zachte stralen (totaal): 26-29; Anale stekels 0; Anale zachte stralen: 23 - 26. Tall, with a small mouth and plate like scales (Ref. 35388).

Biologie     Verklarende woordenlijst (b.v. epibenthic)

Inhabits bays, harbors, lagoons, and seaward reefs (Ref. 9710). May drift with young at surface among Sargassum (Ref. 9710). Usually solitary or in small groups (Ref. 9710). Feeds on benthic invertebrates like mollusks and crustaceans (Ref. 4727). Oviparous (Ref. 205). Consumed mostly fresh, smoked, and dried salted. The flesh is of excellent quality. Because it is resistant to capture, it proliferates and competes for food with other species (Ref. 5377).

Life cycle and mating behavior Geslachtsrijpheid | Voortplanting | Kuitschieten | Eieren | Fecundity | Larven

Adults guard the embryos nested in sand which hatched in about two days (Ref. 9778).
